Optical bench for a stable source of radiation

ABSTRACT

AN OPTICAL BENCH FOR A STABLE SOURCE OF RADIATION USEFUL IN SPECTROPHOTOMETRY COMPRISING A BOX FORMED OF SIDES, A BACK, AND A TOP AND HAVING A DOVETAIL BAR ATTACHED BETWEEN THE VERTICAL SIDEWALLS OF THE BOX. AN OPENING IS POSITIONED IN ONE OF THE SIDEWALLS ABOVE THE DOVETAIL BAR. A FIRST AND SECOND LENS MOUNT IS ADJUSTABLY AND SLIDEABLY MOUNTED ON THE DOVETAIL BAR. A BEAM SPLITTING APPARATUS IS LIKEWISE ADJUSTABLY AND SLIDEABLY MOUNTED ON THE DOVETAIL BAR BETWEEN THE FIRST AND SECOND LENS MOUNTS. A LIGHT SOURCE IS MOUNTED ON A SEPARATE MOUNT BUT POSITIONED IN LINE WITH THE FIRST AND SECOND LENS MOUNTS, THE BEAM SPLITTER, AND THE OPENING IN THE BOX SIDEWALL. ELECTRONIC CIRCUITRY SENSITIVE TO THE LIGHT SPLIT OFF FROM THE MAIN BEAM IS ALSO ADJUSTABLY MOUNTED TO THE BOTTOM OF THE BOX. THE ABOVE UNIT FORMS A COMPACT LIGHT SOURCE FOR SPECTROPHOTOMETRY USES.
